所谓先天性纠正性大动脉转位(ccTGA)即心房-心室-大动脉都不协调。发病率在先心病中<1％,常伴有室间隔缺损、肺动脉狭窄或肺动脉闭锁,及Ebstein样三尖瓣畸形。自然病史的演变差别甚大,与其所伴发的畸形及其严重程度有关。一般讲本畸形可能长期存活,但若伴有体循环心室功能减退和三尖瓣返流者存活率显著降低。常规的双心室修补对那些由形态右室和三尖瓣支持体循环的病例,因其心脏传导组织的部位
The so-called congenital correction of aortic transposition (ccTGA) that atria - ventricular - aorta are not coordinated. Incidence of congenital heart disease in <1%, often accompanied by ventricular septal defect, pulmonary stenosis or pulmonary atresia, and Ebstein-like tricuspid valve deformity. Natural history of the evolution of the great difference, with its accompanying deformity and its severity. In general, the deformity may be long-term survival, but if accompanied by systemic ventricular dysfunction and tricuspid regurgitation were significantly lower survival rates. Conventional biventricular repair of those cases by the shape of the right ventricle and tricuspid valve support cycle, because of its heart conduction tissue sites
